SAFETY DOOR LOCK.

Application filed February 25, 1924. Serial No. 694,958.

To all whom it may concern:

Be it known that we, BYRON G. FRY and DELIA B. RAwsoN, citizens of theUnited States, and residents, respectively, of Glendale and'Los Angeles,Los Angeles County, California, have invented certain new and usefulImprovements in Safety Door Locks, of which the following is aspecification.

Our invention relates to safety door locks,

and more particularly to a simple pocket device which can beconveniently carried in the pocket, or hand bag, and readily applied toa door as it is closed for the purpose of preventing the door from beingopened from the opposite side. It is particularly useful in hotels andboarding houses and can be applied to doors without any cutting orboring of the door or the door frame and without leaving any mark on thedoor.

In order to more clearly explain our invention, we have shown the sameon the accompanying sheet of drawings, which we will now describe.

Figure 1 is a perspective view of one embodiment of our invention, withthe door frame and lock plate indicated in light broken lines;

Figure 2 is a similar view showing the door in closed condition, withthe lock in place for looking it closed; and

Figure 3 is a detail view of the holding pin.

Referring in detail to the drawings, 1, designates a lock plate,provided with the holes, 2, 2, and the angle ear, 3, with a holetherethrough as at 4, to receive a holding pin, 5, shown of split formand bent to an angle, as at 5-. It can be attached by means of a smallchain, 6, if desired, to the lock plate 1, as indicated. Said lock plateat its inner end is provided with a projection, shown to be two struckout or stamped lugs, as at 1' 1*, adapted to be inserted into the boltrecess 7, in the door frame, as clearly shown in Fig. 1, when said lockplate 1 is put flatwise in place. This prevents said lock plate 1 frombeing pulled straight out lengthwise, as will be readily understood. Thedoor is closed on said lock plate 1, as will be understood from Fig. 2 Alatch or holding member, 8, is adapted to be placed on said lock plate1, and has an angle ear, 8, adapted to rest against the face of thedoor, D, as shown, said member 8 being also provided with holes, 8,adapted to register with the holes, 2, in the lock plate 1, as it is putin place in the manner indicated in Fig. 2. The holding pin 5, throughthe angle ear 3, is then inserted through the lock plate, 1, and theholding member 8, as shown. The split angle portions of said holding pin5, yieldingly hold the same in place in the holes, as will be readilyunderstood from the showing in Fig. 2. In order to release the lock, itis only necessary to swing the outer end of said holding pin 5,forwardly so as to move the split angle part 5 thereof out of the holes2 and 8, and the door can be readily opened, moving the member 8 alongthe lock plate 1, or sald member 8 can be removed by hand before thedoor is pulled open. It will be seen that when the lock'is in place, asillustrated in Fig. 2, that said door D, cannot be opened, for the lockplate 1, is held between the edge of the door and the door frame, and itcan not be tilted to release its holding lugs l, for the reason that itsinner end projects beyond the edge of the door-bolt hole 7 as seen inFig. 1.

Thus we have provided a very simple, economical and efficient safetylock for doors, and while we have illustrated only one form of ourinvention 0n the accompanying drawings, we are aware that changes can bemade in details without departing from the spirit of the invention, andwe do not limit the invention to the showing made, except as we may belimited ed to bear flatwise against a door when and saidslideholdingmemher,substantially closed and having holes to registerwith the as described. holes in said plate member, and a pin in- Signedat Los Angeles, Los Angeles 10 serted through the hole in the angle partCounty, California, this 15th day of Febru- 5 of said plate member andhaving its inner ary, 192%.
